' HILTON C. J. BILLINGHAM, OF KALAMAZOO, MICHIGAN? PAIER-STOCK-TREATING Macnnm Specification of Letters Patent.

Patented July 19, 1921.

Application filed April 23, 1920. Serial No. 876,058.

To all whomitmay concern:

Be it known that I, MILTON C. J. BILLING- HAM a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Paper-Stock-Treating Machines, of which the following is a specification.

:Thi's vention relates to improvements in page! took treating machines.

Y y-iimpreved stock treating machlne 1s especihlly designed by me for use in disintegrat-ing old papers foruse as paper stock andlor deinking such stock.

- The main objects of this invention are:

a 2 First, to provide an improved disinte ratingordefibering machine in which the here ing machine in-which all of the stock is efiectively treated oracted upon.

"Further objects, and objects relatin to s trnctural details will definitely appear rom the detailed description to follow.

, m lish theobjects of my invention by thedevioes and means described in the follewing'specification. The invention is clearly defined and ointed out in the claims.

A structure whic is a preferred embodi ment of my invention is clearly illustrated in the accompanying drawing =forming a part ofthis" ecific'ation, in which:

Figure I is a detail view partially in vertical central section of my improved stock 2 treatin machine or apparatus.

mFi'g. "is a plan view thereof. is a horizontal section on a line corresplonding to line 3-3 of Fig. I. Int

e drawing similar reference charactens refer to similar parts throughout the several views. In the'accompanylng drawing, I have not attemped to show or maintam theaproper relative proportion of parts asuthese'will be" greatly varied to suit the capacity and the'particular condition of installatio'n, and various parts are shown in conventionnlform.

. Referring to the drawing, I provide a cy lindrical tankl. disposed vertically and provided with an internally concave bottom .2

having a discharge 0 ening 3 and an internally curved to 4. 'Fhe dlscharge pipe 5 is connected to t e discharge 0 ening 3 the pipe having a connection 6 or the a mission of the stock to be treated and the deinking solution and branches 7 connected to the intakes of the pumps 8. One of the pumps 8 is provided with a discharge pipe 9 disposed centrally through the opening 3 of the tank to project centrally withln the tank. On the upper end of the pipe 9 is a nozzle 10.

The conical deflector 11 1s mounted on this pipe with its lower end 12 spaced from the bottom of the tank so that the stock may flow below the deflector to the opening 3. The second pump is provided with a discharge pipe 13 terminating in the nozzle 13' disposed vertically through the top of the tank in alinement with the nozzle 10 and in a spaced relation thereto so that the streams from the nozzles impinge centrally within the tank and at the upper end thereof. The pipe 13 is rovided with a connection 14 for the admisslon of steam or water and a connection 15 for the discharge of the treated stock.

In the structure illustrated, an electric motor is indicated conventionally at 16.

With the parts thus arranged, the stock to be disintegrated is delivered through the nozzles in impinging streams at the upper end of the tank. As these streams impinge centrall the material is quite uniformly distributed in the tank and flowsuniforml to the discharge opening, that is, it is not li ly to clog or bank up within the tank or adhere to the walls thereof, the upper end of the tank being curved so that the discharge from the nozzles prevents the pieces of paper or the like from adhering thereto.

It is of importance that all of the material treated circulate for the reason that should a portion fail to circulate for a time and then become dislodged, the stock is not Uniformly disintegrated and is not suitable for the purposes intended.

My improved machine is especially well adapted for the treating of stock with deinking solution as the stock is not only uniformly treated but is effectively disintegrated without any grinding action which would beat or grind the ink into the fiber and thus prevent its being entirely free.

By the aid of this apparatus, I am enabled to disintegrate fibrous material such as printed paper to substantially its original I rial is entirely suspended in the carrying pulp condition, that is, the fibers are not shortened or broken up as by grindin or coming in contact witha hard unyielding surface as the disintegration is eifected by a. pulling or tearing action while the mateli uid. 1

Iaving thus described my invention, what I claim as new and desire'to secure by Letters Patent is:

-1. In a stocktreating machine, the com bination of a vertically disposed cylindrical:

tank having an internally concave bottom with a central discharge opening. therein and an internally c'urvedtop, pumps having their intakes connected to' said tank discharge, a discharge pipe for one'of .said pumps provided with a nozzle and disposed vertically in saidtank and centrally through said discharge opening thereofwith its nozzle near the upper end of-the tank,'a discharge pipe for the other pump provided Witha nozzle disposed vertically and centrally through the top of. the tank, said nozzles being in.

2 *alinement and spaced so that the streams therefrom impinge, anda conical deflector mounted on the first mentioned discharge pipe and having its bottom spaced from. the

bottom of the tank to permit the flow of stockto said tank discharge opening.

I 2. In a stock treating machine, the combination of'a vertically disposed cylindrical tank having an internally concavebottom with a central discharge opening therein and an internally curved top, pumps having their intakes connected to said tank discharge, a dischar e pipe for one of said pumps provi.ded w1th a nozzle and disposed vertically in said tank and centrally through said discharge opening thereof with its nozzle near the upper end of the tank, and a discharge pipe for the other pump provided- .with a nozzle disposed vertically. and censaid nozzles being in alinement and spaced so that the streams therefrom impinge, and a conical deflector mounted on the first mentioned discharge pipe and having its bottom spaced from the bottom of the tank to permit the flow of stock to said discharge opening." i

4. In a stock treating machine, the combination of a tank having a dischar e opening in its bottom, pumps havino' t eir intakes connected to said tank discharge, a

discharge pipe for one of said pumps provided with a nozzle disposed vertically in said tank, and a discharge pipe for the other pump provided with a vertically disposed nozzle, said nozzlesbeing in alinement and spaced so that the streams therefrom impinge.

5. In a stock treating machine, the combination of a cylindrical tank disposed vertically, a conical deflector disposed centrally within said tank with its lower. end spaced from the bottom thereof sothat the stock may flow below the deflector to a central dis-, charge opening, a nozzle disposed at the apex of saiddefiector to delivernpwardly,

a second. nozzle disposed to deliver down-L Wardly above said first nozzle andin-alinement therewith so that the streams therefrom impinge, and pumps having their in takes connected to the. bottom of said tank and their discharges connected to saidnozzles, all coacting for the purpose specified.

6. In a stock treating machine, the combi-, nation of a vertically disposed cylindrical tank having an internally concave bottom with a central. discharge opening therein and an internally curved top, nozzles disposed 1 within said tank at the upper" end thereof so that the streams therefrom impinge centrally of the tank, a conical deflectordisposed centrally of said tank below said nozzles and over said discharge opening, and means for circulating the stock from said discharge opening to said nozzles.
